My custom requested interlocking rings arrived yesterday and will be in the mail to the buyer today... Thought I'd give you guys a look-see. If I had to re-design these I'd make the outer "arms" thicker as that silver is very thin... but the design works, anyway.

That's a great design! It's good to hear your redesign ideas for the next version. That second photo, with the overlap, would make a nice pendant or earring done as a single object. It shows the relationship of the two without being completely closed.
